more particularly refers to improvements in cushioning devices for shuttle: binders such as are currently used in box looms for checking the.

movement of theshuttle at the end of its stroke.

vIn the great majority of looms which have.

. come to our notice, the movement of the shuttle is checkedby a binder consisting of a. curved metallic arm pivotally mounted at one of its ends and pressed inwardly by a spring, causing itto yieldingly bear against the side surface of the shuttle as theshuttlereaches the shuttle box.

\ .When-the shuttle reaches the: extremepend of its-movement in one direction, the weft or filling which unwinds from a spool carriedby the. shut .tle extends rearwardly. of the shuttle directly vfromthe inner endthereof. However, when the shuttle reverses its movement the weft or filling which unwinds from the same end of the shuttle is turned backward and runs along the adjoining side surface of the shuttle, said surface being the type of clip whichcan be employed for the same one which comes .into contact with thebinder when the shuttle reaches the end of its stroke.

Althoughthebinder yields easily when the" side surface. of the shuttle bears against it, the impact, and the. friction developing between the metallic surface of the binder and the hard polished surface. of the shuttle frequently cause the thread used: as a weft or fillingto break. This necessitates stopping of the loom and fastening of the broken ends of the thread and results in a considerable loss of time both for the loomand the attendant. H i

- The primary object or this invention istopro- I vide cushioning means ;fortcovering the surface of the binder, adapted to partly absorb the imjected, during the period in which the shuttle travels for the length of the binder..

Another. object is toprovide a web protector forbinders adaptedto be easily secured in position and to be easily removed therefrom and replaced by another similar device when required. H Afurther object is, to provide anovel and improved device of the character specified comprising a strip or web of fabric possessing a certain resiliency and a thickness sufficient to produce a causing it toresist wear and to last for relatively long periods of time. N i 1 A still further object is to provide a protective devicefor binders of the character specified,

effectively prevent breakages and thus permitthe fastening clip. pact of the shuttle, and to nullify or greatly diminish the-friction to which the thread is subor bulging outline and is pivotally mounted" at 32 and is pressed inwardly by a spring 33 causing This invention relates to textile machinery and uninterrupted operation of aloom for relatively long periods of time.

Other objects and advantages of the present invention will more fully appearas the description appears'and will beset forth and appended claims. i

Our invention is illustratedby way of example in theaccompanying drawings, in which: n 1 I Fig. l isa top plan view of aportion of a lay. beam, and shuttle box showing. the binder bearing Fig. 4 is a front .viewofi the binder protector shown in Figs. 1 and 2 n Fig. 5 is a View in perspective of one of the clips used to .grip and fasten each end of the fabric forming part of the deviceshown in Fig. 4;

Said weft or thread emerges from the side of the shuttle at 28 and is turned rearwardly alongthe' side 29 of the shuttle, so that said weft or thread normally rubs against the inner sur face 30 of the binder 31 whenthe shuttle moves towards the right to the extreme position shown cushioning effect, said fabric having a structure in Fig. 1. The binder31 has an inwardly curved itto bearyieldingly againstthe side surface of n the shuttle. which: is relatively inexpensive and whichshall I the weft or. thread, we equipthat portion of the In order to prevent excessive friction against claimedirr the curved surface of the binder which is likely to come in contact with the side surface of the shuttle with a protector consisting of a strip 34 of yielding material extending longitudinally of the binder directly against the inner surface thereof, and secured in position by suitable fastening means, for instance, by means of end clips 35. The manner of applying the protective device will bel'bestuunder'stood:from Figs. 2 and '3, which illustrate "the"- conventional type of binder used in the arrangement of Fig. 1. From said figures it will be observed that the central curved. portion of the binder is relatively widetand isicon-.

nected by two narrower or neck portions3'7j38 to its outer end 39 against whichs'bearsifthe.tpro-m. tector finger 23 and to its hub or pivotal support:

32 respectively. It is therefore feasible to provide a protecting strip e'xtenfding'fonthe' entire length of the wider central portion 36:.and 5secured in position at the strangled points 39, .40 where said'wi'der portion joins the neck "portions 37, 38.

By 'thus taking *advantage. of the shoulders "formedby the endsofthe wider central portion, it

is possible to secure" the "protective *strip tightly in posi tion, so that it Will closely adhere to the "surface 34 )of the I binder, precluding the possibility.ofitsbecomingloose or wrinkly. I i

:As stated ;above,- the fabric should possess both a oushidningeffctandagood resistance to wear, tl'ferefore itshdulfd'bea; woven fabricin" preferj ence to feltfand itshould'be' sufficien'tly thick and soft toIperinitthe "weft-or thread to-become embeddedthereirr during the movement of the shuttle. .We have found that very good results can "be obtained'by using as a protective strip, webbing such as used for instance, in making wicks "for alcoholandoil'jburners. Such a type of fab- 'ric hasiits main interwoven strands runningin a "diagonalfalmost' longitudinal direction, and {thereforefiswell 'apt'to withstand rubbing action which is "exerted"*substantially in the" direction in which .the fibers of such strands run. At the "same'timesuch a type of 'fabric is comparatively soft and heavy and well adapted to provide the ,neededfgive. or 'cushioning effect.

. ""However there are "undoubtedly other-types of f fabrics "or feltsthat-car'r be used to good advantagerandfitherefore we donot wish to be restricted in this respect to-any particular fabric or nratei'iali :For instance, a protective strip might? -beimade "of a suitable grade "of rubber,

although "we are aware that sponge rubber has ibeemusedjbefore'as an-integral part of a binder and hasnotproved very satisfactory, due to the fact that rubbing and heat are likely tocause the rubber to harden and "to -'dismtegrate,- and "also affect itsresiliency.

"In "order "to facilitate and enhance the practical use-"of-the device itis'preferabIe to equip "eachend-"of the protective I strip with fastening 'means-forming-an integral part of the device fand doing away-with the necessityof using strings-or otherfaste'ning means detached from "the stripand 'apt to become loose in service or fto 'become displaced. The fastening means can beof any 'suitable design. For instance, in Figs.

- 1,-2; 4;5-,-we illustrate clips' made of thin, soft metaL each*clip =beingbbtained from a cross '=at 41',-forming-a double thickness T shaped clamp shaped blank-bentmidway of its width as shown having two longitudinal extensions42, 43 acting .as means for fastening the device onto the binden andtwo inwa-rdlyextending jaws 44, 45

' ii provided withprongs such as I 46 adapted to grip .49 .are .punchedout of the central part of the strip andare bent downwardly, constituting means .for-apiercing the fabric, said prongs being adapted to be turned outwardly or inwardly so as to form a permanent connection between the strip and the fabric.

Iii-Figs. 7, 8 and 9 we show a still different type of fastening or clip which consists of a thin strip of metal 50,- sirnilar to that of"Fig.'6, that is, formed with two p'ron'gs' "51, l 52 adapted to go through-the fabric 53 and to bewbentj oven-as shownin Fig. 9.

- a One of the ends of strip is provided-"with two openings 54,55, and the other end is'prov ided with atongue' 56 extendingdengthwise therefrom. Such a fastening 'device or clipis-per-ma- .nently secured onto'ea'ch end' of the fabric by means of prongs. 51, 52. and whenfithe protective-'deviceis placed. in position; "the". strip".to-
